These notes assume that the pilot already has some experience of operating a variable
pitch propeller. The UK CAA strongly recommend pilots to undergo ’differences training’
before they are allowed to operate aircraft with variable pitch propellers
9.7. NORMAL PROCEDURES
In order to set the propeller to FINE for start-up, take-off and approach use the following
procedure:

Press rocker in direction FINE (forward or top position), status indicator FINE
flashes, engine RPM increases

Keep rocker depressed until end position is reached (status indicator FINE steady

To adjust the propeller to a COARSER setting use the following procedure:

Adjust propeller pitch and throttle to match engine RPM and manifold pressure
according to the power setting table below
